Pulse output waveform of PLC?

Panasonic's has never been used. As you said, the output port is activated at low level. If the pulse is output directly through the output port, the structure will not change, and it is still active at low level, jumping from 24V. If the output port is connected to the +24V power supply, it cannot be directly connected to the stepper motor driver. The pulse input of the driver is generally 5V, so a resistor should be added.

But in my experience, I seldom use the output port to output the pulse directly, except to save the cost, because the frequency of the output pulse is limited and not high. Are you talking about a special position control unit? Then consider wiring. Each pin has a special definition, which is generally an NPN open-collector output. Pay special attention to the connection here. Generally, there are two kinds of power supplies, +24V or +5V. You can't make mistakes. You'll burn something. It is best to find this information to confirm.

I have a simple example at hand, for reference only, to see if it helps.

The inside of the pulse unit is usually an NPN transistor of open collector, and the inside of the driver side is usually an optocoupler. It's best to find the information to confirm it, so as not to connect it wrong and burn out the components.
